11.3.2 Real-time data object registers

The data changing in real time, such as current, voltage, power, etc. are shown in the table

below. Real time data can be obtained either in IEEE floating point or in fixed point format.

For data shown in fixed point format, each result would be the real time data multiplied by

a scale factor. The scale factors are shown as the last column in the table. Energy objects

can be only obtained in fixed point format.

Each data object occupies two registers (four bytes) in length except for certain energy

objects. These energy objects occupy four registers. Since these objects have the capability

to change in real time, a complete data object must be obtained in a single transaction to

avoid data tearing. Attempting to access a partial data object will result in an exception code

84. Refer to a later section entitled “Exception codes”.
